State-of-the art digital control is used in all CINERGIA products. In the DCPS case, the control
system algorithms are computed in a dual core DSP-based hardware, designed by CINERGIA,
allowing a multitask execution of the regulation systems for the Active Rectifier and the DC/DC
output. This produces a fast transient response and high performance against load changes. A
12 bits analog to digital conversion, with digital processing, allows a high resolution output up
to 0.1% with high stability too.
Resonant control
Control algorithms based on Resonant Control are used in the AC side. The regulation is
structured in blocks resonating at a given frequency. Within the resonant frequency each block
allows the suppression of gain and phase errors of the controlled magnitude: voltage, current,
…etc. Thanks to this, each harmonic can be controlled independently and thus it can be
generated or suppressed, as needed.
PID control
The DC side control algorithm is based on a traditional PID controller which will be explained
later.
